Several iconic K-pop groups are making highly anticipated comebacks after years of being on hiatus, with the resurgence of retro pop being a key factor driving this trend. Despite reasons such as legal disputes, contract expirations, or individual pursuits, former top K-pop bands are reuniting to satisfy fans' desires to see their favorite idols back together. Notable examples include 2NE1 from YG Entertainment, who are set to reunite after eight years with a concert in Seoul, and JYJ's project group JX, consisting of members from TVXQ, reuniting after five years for their 20th debut anniversary. The cyclical nature of music trends, coupled with fan demand and personal motivations, are also contributing to these comebacks. GFriend, a group that debuted a decade ago, is reuniting next year after nearly four years apart, showcasing the increasing longevity of K-pop idols' careers. The overall cultural landscape of K-pop is being revitalized through these reunions, with management coordination and timing playing crucial roles in bringing these groups back together for their fans.
